The latest OSX JDK won't work with IDEA until we get a fix from you guys, the issue is:
KEY_TYPED events were being generated from the Swing event thread, and were synthesized from INPUT_METHOD_TEXT_CHANGED events. This behavior was incorrect, and has been fixed in 1.4.2 Update 1 DP2. KEY_TYPED events are now generated directly from keystrokes and are posted to the AWT event queue. IDEA was working around the bug, and the fix now breaks current versions of IDEA.
So, please give us a build that fixes this!
